Abstract:


This paper conducts a new context-aware clustered routing approach for video transmission over VANETs (CACVANET) that tries to make vehicles communicate with each other using a context-aware concept which is achieved by real-time monitoring and exchanging relative velocity and distance. A Context-Aware Cluster (CAC) of nodes is formed based on the context of trajectory, relative velocity, and distance between vehicles in the same trajectory direction. It tries to guarantee long lifetime paths for successful data and video transmission over VANETs, which can be achieved by maximizing link lifetime which leads to higher connectivity and Long Lifetime neighbourhood (LLN). This paper demonstrates the idea and modelling of CACVANET approach with assumptions and scenarios of both cases: with CAC concept and without CAC concept. The implementation and evaluation of CACVANET approach will be a future work of this study. Due to the realistic nature of the CAC concept, we expect that CACVANET approach will outperform traditional protocols in terms of the most common performance metrics such as energy consumption, delay, and routing overhead.
